The longshot, ridden by Javier Castellano, was bumped by leading She’s A Tiger, ridden by Gary Stevens, down the stretch. After a five-minute inquiry, She’s A Tiger, which led the entire 1 1/16 miles, was disqualified.

“The first thing Javier said to me,” trainer Jeremiah Englehart said, was that he got bothered. “He said she bothered us enough.”

Ria Antonia was well behind She’s A Tiger, but the Jeff Bonde-trained horse began fading. He drifted out into Ria Antonia’s path.

“I thought at 29-1 she would probably fade at some point,” Englehart said. “When I realized she could win the race I thought to keep your clothes on, act professional.”

Secret Compass, ridden by John Velasquez, was running second when she went down. The Bob Baffert-trained horse was euthanized after falling entering the back turn.
